I'm not sure but the parts guy at Auto Zone will look it up for your Vette and give you the right part.

many parts like that,gas caps,wiper blades etc,are surprisingly priced at the dealer.
i always check there first (just call)when it comes to the vette.
wiper blades were cheaper than napa the other day.whodathunkit.
oh yea,i did buy a rad cap for my 92 at the dealer last year,didnt price it,just wanted the correct look under the hood and the one they had was identical to the old one.

My stock cap was 16 PSI, it was in bad shape so I got a new 16 PSI cap with the vent valve to release pressure into the over flow should you need to. It's a handy feature. I've a friend with a '95 T/A and '00 Firehawk, they both have 18 PSI caps. My cooling system works well so I stuck with stock PSI.

My 85 and 88 both have the HD radiator and the factory cap was rated at 17 PSI. I could not get a 17 psi cap at any aftermarket store so I bought an expensive AC Delco from Chevy.
